Got some OGV files you want to convert to MP4? Then you've come to the right place. This article discusses the fastest ways to convert OGV to MP4 on Windows and Mac while retaining the original video quality.

Before we dive into the how-to steps, you may want to get to know some basics about OGV format and what we can benefit from changing OGV to MP4. Or you can jump to a section you are interested in with the navigation.

 

What is OGV?

OGV stands for OGG Video, a video file format developed by Xiph.Org Foundation as part of the OGG multimedia framework. It typically uses Theora video codec and Vorbis audio codec. OGV video files are often used for HTML5 video elements in browsers and open source projects like Godot due to their royalty-free nature.

OGV vs. MP4: Why Convert OGV to MP4

While OGV has its advantages as a free and open source format, converting it to MP4 can provide you with:

• Higher compatibility on computers, mobile devices and streaming platforms
• Better quality to file size ratio. MP4 is generally superior to OGV with more efficient compression, making it ideal for storage and streaming.
• Easier editing and sharing.

3. FFmpeg

FFmpeg is a command line tool that can convert almost any video and audio format. While it's extremely flexible and powerful, it has a steeper learning curve if you know little about the command line interface.

How to convert OGV to MP4 using FFmpeg on Windows and Mac:

1. Install FFmpeg.

Visit the FFmpeg official website and download the latest version for your computer. Put FFmpeg in a directory that is easy to find, such as Downloads.

2. Open Command Prompt (on Windows) or Terminal (on Mac).

3. Use "cd" command to navigate to the folder where the FFmpeg is located. For example, type cd downloads and press Enter.

4. Run the conversion command: ffmpeg -i input.ogv output.mp4

Replace “input.ogv” with the name and path to your OGV file and “output.mp4” with the wanted output file name.

With this basic command line, x264 and AAC codecs are chosen by default for the MP4 file. When conversion is completed, you can find the converted MP4 file in the same folder of FFmpeg.

Additional options:

1. Convert an entire folder of OGV files to MP4 with ffmpeg, use the following command line: for %i in (*.ogv) do ffmpeg -i "%i" "%~ni.mp4" Mac users use: for i in *.ogv; do ffmpeg -i "$i" "${i%.mp4}.mp4"; done

2. Add "c:v" and "c:a" to specify the video and audio encoders, and "q:v" to set a quality level. For example, ffmpeg -i input.ogv -c:v libx265 -c:a ac3 -q:v 6 output.mp4

The video quality (q:v) can range from 1 to 10, with 6 providing a balance between quality and file size.

You can learn more command options from the FFmpeg documentation page.

Final Thoughts

It's worth mentioning that if you convert from MP4 to OGV without configuring settings, the video may become low-quality and stuttering. So it's best to keep your original OGV file for future use, or use a dedicated video converter that automatically preserves the best quality whether converting to or from OGV Theora format.
